Could this be a bad transmission pump?

So I've been doing some research but what do you think the chances are that the noise could be a worn parking pawl?? My truck does roll a little after putting it in park and there have been times where it's hard to get out of park. @NickTransmissions I don't know if you've seen the video, any help or advice would be greatly appreciated
Drop the pan and take a look for debris for broken parts. We can speculate all day long but be no closer to an answer; got to get "hands on".

Also, it's perfectly normal for the vehicle to roll a little bit before the next lug on the parking gear/rear hub rotates into position for the pawl to engage. Having it be a little tough to disengage, especially on grades is also normal.

Ok and I agree I have to get hands on, so today while my father in law was going back the house he said the transmission overheated, he made it to the house, but I know I need to check the cooler and fluid, I'm pretty sure the filter also, but is there anything else I should check? I know I can check the transmission lines, but I don't know how. Would I get a pressure gauge on it?

I just watched your video and the sounds heard towards the end appear to be external to the transmission or engine...Perhaps flex plate hitting the TC cover, dangling heat shielding or something similar. I normally don't diagnose or even suggest anything based on videos as most are shot with cell phones that really can't render the sounds in a way that helps pinpoint or accurately characterize the sound - just a limitation of the tech...

You can do a pressure test by installing a transmission pressure gauge into the 7/16 pressure port tap on the driver side of the transmission, just rearward of the bell housing...If your line pressures are good (55-80 PSI in P, N, D, D3 and 90-120 PSI in Reverse) at idle, then pump is probably fine.

Check for burnt clutch material, metal, etc once you drop the pan. Also cut the filter open to see what it's been collecting. Overheating episodes are no good and depending on length / severity, soft part damage my have been sustained though won't know until you try driving it again after the service.

If you see a bunch of chunks, black charred clutch material, metal flakes, pieces of gear teeth, etc just put the pan back on w/ a few bolts and yank it out for overhaul...

Transmission over heating? Either a bad lock-up, or a failing planitory gear.
If the transmission begins to smoke,... drive EASY...... Accelerate as if you are driving on ice.
This will make the transmission slip less ( slipping causes heat). Then go straight to a transmission shop.

Well, you can't hurt the transmission any more than that, until it comes to a stop. Save your towing cost..... Make an appointment at a good transmission shop and drive there while you still can.

Sucks, man....Time to yank it for overhaul....check input sprag, it may have rolled over which results in a loss of forward movement in DRIVE. D3-Manual low will work due to coast clutches and, in man low - low reverse clutches/low roller active.

I agree with you but I don't have any money for an appointment or shop, right now I do have a ride figured out to work, thankfully I live close but I'm going to have to save up and then take her in

Yea... save your dollars then fix it. Hang in there..... Once you fix it, or replace it, ..it will be good for a LONG time !

It looks like right now I might be waiting on income tax and then I'm going to be doing the lifters also, which I got to get more knowledge on what all I'm going to have to replace on that also I know if the lifters are worn I gotta check the cam, but I gotta do a lot more research first. Are there any overhaul kits that I should stay away from or anything that I should be looking for specifically to get?
